Thanks for the comments and information everyone. Good input that is helpful to me. When I saw galvanized cables I kind of wondered if they would not slide as well in the housing, thinking of how the surface of a galvanized piece of metal feels compared to the smoother surface of a stainless piece of metal. I was not aware of Velo Orange cable sets or of Pork Chop's cable sets. It is interesting the ordering options Pork Chop lists in their descriptions. So based on the comments, I think I will stick to stainless steel cable and go shopping for better quality housing.
